Hope, I wonder what made you even ask the question about staying in touch, if you haven't been thinking about him?

I think the suggestions to distance from him are good. Try moving your prescriptions, or have someone else pick them up and make any phone calls that are needed. After some time (possibly a while) with no contact, you may see that these feelings aren't there or as strong anymore. On the other hand, they may still be there. If that is the case, see if he really did mean yes when he answered this question. Sometimes, relationships start from the most unlikely of places, and it could be possible that is the case here. However, the fact is that currently the relationship is a professional one, so to test that, the professional part would have to end.

Like was said above, I think trying to make connections with people that there is no prior professional relationship would be a great idea! Even just to have other friends, or more friends... I've never tried meetup myself, but I have heard great things about it. You can connect with people you have things in common with already.

It just seems, to me, that a lot of the professional relationships you have had (a lot may be incorrect, but the pharmacist is not the first or even second as far as I can tell) have led to a level of obsession. Even without acting on urges to contact people inappropriately, the mental obsessing you seem to go thru is not healthy and *may* have a part in some of the other issues you experience. I don't know much about what all you deal with daily, mental health related, but I remember reading at one point you were too depressed to leave the house, from a reaction of this pharmacist.
